text-decoration-thickness

The text-decoration-thickness CSS property sets the stroke thickness of the decoration line that is used on text in an element, such as a line-through, underline, or overline.

Values: auto The browser chooses an appropriate width for the text decoration line. from-font If the font file includes information about a preferred thickness, use that value. If the font file doesn’t include this information, behave as if auto was set, with the browser choosing an appropriate thickness. <length> Specifies the thickness of the text decoration line as a length, overriding the font file suggestion or the browser default. <percentage> Specifies the thickness of the text decoration line as a percentage of 1em in the current font. A percentage inherits as a relative value, and so therefore scales with changes in the font. The browser must use a minimum of 1 device pixel. For a given application of this property, the thickness is constant across the whole box it is applied to, even if there are child elements with a different font size.

Syntax example: text-decoration-thickness: auto;
